For these reasons, in on-board programming mode alone there are conditions for disabling NMI
input, as an exception to the general rule. However, this provision does not guarantee normal
erasing and programming or MCU operation. All interrupt requests (exception handling and bus
release), including NMI, must therefore be restricted inside and outside the MCU during FWE
application. NMI input is also disabled in the error protection state and while the P or E bit
remains set in FLMCR1 during flash memory emulation in RAM.
Notes: 1. This is the interval until a branch is made to the boot program area in the on-chip RAM
18.10
The H8/3024F-ZTAT version has a PROM mode as well as the on-board programming modes for
programming and erasing flash memory. In PROM mode, the on-chip ROM can be freely
programmed using a general-purpose PROM writer that supports the Renesas Technology
microcomputer device type with 128-kbyte on-chip flash memory.
18.10.1 Socket Adapters and Memory Map
In PROM mode using a PROM writer, memory reading (verification) and writing and flash
memory initialization (total erasure) can be performed. For these operations, a special socket
adapter is mounted in the PROM writer. The socket adapter product codes are given in table
18.10. In the H8/3024F-ZTAT version PROM mode, only the socket adapters shown in this table
should be used.
2. The vector may not be read correctly in this case for the following two reasons:
Flash Memory PROM Mode
(This branch takes place immediately after transfer of the user program is completed).
Consequently, after the branch to the RAM area, NMI input is enabled except during
programming and erasing. Interrupt requests must therefore be disabled inside and
outside the MCU until the user program has completed initial programming (including
the vector table and the NMI interrupt handling routine).
• If flash memory is read while being programmed or erased (while the P bit or E bit
• If the entry in the interrupt vector table has not been programmed yet, interrupt
is set in FLMCR1), correct read data will not be obtained (undetermined values will
be returned).
exception handling will not be executed correctly.
